Van Buren, ME or St Leonard, NB, Canada

[rosegramma]

Will be attending an event in Van Buren, ME first week of Aug. Don't know anyone there. Closest campgrounds I can find are Grand Rivere, Camping St Leonard, or Maple Leaf Motel & campground, all on Canadian side. My cell service doesn't allow international calls and when I tried Skype, could only get a recording in French, which I don't understand.
Does anyone know if any of these campgrounds are suitable for a 40 ft DP? I did email Grand Rivere, and got a positive response, but would like more info from someone who knows the area or has been there, and would like to know how I can contact the other campgrounds as I can't find an email or website for them. Also wondering how much hassle it will be making the border crossing in our toad each day. The closest US campgrounds I can find are well more than 1/2 hr away. Any help appreciated.
